Why is "my" Crystal Ball nebula green instead blue ?

Hi everyone,
recently, I tried to capture NGC1514 - Crystal Ball nebula with my small 60/360 refractor and the Neptune-C camera.
Sharpcap Livestack - exp 15s, offset 150, gain 400, Darks, 3900 frames
In addition to the built-in UV/IR cut filter, I used a Skywatcher LPR.
Despite to the images I have seen in the internet, "my" Crystal Ball came out in green colour instead of blue.
I played with the settings in postprocessing, split the channels, recombined it, etc., but nothing changed.
Then, while combining the RGB channels, I swapped G and B and guess what I've got ? A blue crystal. :o
What's wrong or why is its so ?
